Application filed November 29, 1913. Serial No. 803,825.

To all whom it may concern:

Be it known that I, CLARANCE R. BRYANT, a citizen of the United States, residing at Fort lVort-h, inthe county of Tarrant and State of Texas, have invented new and useful Improvement in Packing-Rings, of which the following is a specification.

The invention relates to an improvement in packing rings involving a plurality of ring structures adapted to be readily and quickly assembled or disconnected when desired.

The main object of the present invention is the provision of a packing ring involving inner and outer ring members, each being transversely divided and the respectiverings being formed with cooperativemeans to prevent independent rotative movement thereof when in assembled relation.

-The invention in its preferred form of details will be described in'the following specification, reference being had particularly to the accompanying drawings, in which Figure 1 is a perspective view illustrating the improved packing ring. Fig. 2 is a perspective view of the outer ring member. Fig. 3 is a perspective view of the inner ring member. Fig. lis a view in elevation illustrating the means for preventing independent rotation of the ring members. Figs. 5, 6, and 7 are broken detail elevations illustrating dif ferent forms of terminal joints of the inner ring member. Figs. 8 and Q are sectional views of the respective ring members of the dillerent forms of packing ring. Fig. 10 is a sectional view of the respective ring members of the different forms of packing ring.

Referring particularly to the accompanying drawings, the improved packing ring for pistons comprises an inner ring member 1 having an outstanding annular bot-tom flange 2, the latter projecting beyond the outer surface of the ring pistons equal to the outer thickness of the outer ring to be later described. The inner ring is divided across as at 3 forming in effect a strip bent into ring form and having the meeting ends cut so as to provide an offset juncture. As shown inFigs. 1, 2, and 3, the meeting ends of the ring member are on diagonal lines, while as shown in Figs. 5, 6, and 7, they are cut on distinct and relatively different lines. In this connection, it is to be understood of 5 comprises an annular member having a thickness corresponding to the width of the ledge 2 of the height. corresponding to the height of the ring 1 above the ledge. The outer ring member is designed as will be apparent from Figs. 1, 2, and 3 of the drawlugs, to fit on the ledge and in contact with the outer surface of the inner ring member, and said outer ring member is also divided as at.6, the. formation of the meeting edges of the division being that illustrated in Figs. 1, 2, and 3 of the drawings, or that shown in Figs. 5, 6, and 7, as may be found desirable. One of the edges of the line of division of the outer ring is undercut to form a recess 7 designed to embrace the pin when the parts are in connected relation, as shown in Fig. 1 of the drawings.

In Figs. 8 and 9 I have shown a slightly different form of inner ring member in that the ledge or flange 2 is downwardly and in wardly inclined on its upper surface as at 8, the lower surface of the outer ring member 5 being correspondingly downwardly and inwardly inclined.

In Fig. 10 I have shown another form in which the ledge 2 of the outer ring member is downwardly and outwardly inclined on its upper surface as at 9, the lower surface of the outer: ring member being correspondingly downwardly and outwardly inclined to iiiterfit with the surface 9, as shown.

From the above, it will be obvious that I have provided a simple form of packing ring in which the parts are adapted for ready connection or disconnection, and in which when assembled, they are held against such independent movement as'will tend to interfere with their effective cooperation with the bearing surface.

What is claimed is A packing ring including an inner ring member, formed with outstanding ledge at one edge, the member being divided and formed'to provide interfitting ends, a pin projecting from the ring member, and an outer ring member resting upon the ledge and contacting with theinner ring member, said outer ring member with respect to the said outer ring member being divided and inner ring member. 10 formed with interfitting ends at the point In testimony whereof I aflix my signature of division, one of said ends being formed in presence of two witnesses. I with recesses to coiiperate with the pin, the CLARANCE R. BRYANT. meeting surfaces of the ledge and outer ring Witnesses: member being formed for interfitting to R. E. BROWN, prevent a relatively outward movement of I. T. HOUSTON.
